Little charms in new house? Sanskrit?

A friend of mine just bought a new apartment, and as we were lugging in her endless boxes of books (I’ll never help a pair of academics move, ever again!), I noticed these little quarter-sized papers stuck to the walls, in the middle of each wall by the ceiling, of circular, symmetrical symbols. From below, and not close up, they seemed to be the shape of that japanese coin that is round with a square hole in the middle. Each was a different color, red, yellow, green, possibly blue. They were in every room of the house.

Now, the only other clue to these symbols is that there is a little Ganesh stuck up above the doorway from the outside. I’m not at all familiar with sanskrit or hindu symbology, and neither is my friend, but she plans on keeping them up.

Does anyone have any idea what these papers are or what they’re supposed to represent?

Almost halfway down this page is writing in a bunch of languages:

Does it look like the writing on the papers on your friend’s wall. Which language does it look more like?

Oh gosh, I don’t think there was any writing on them, they looked more like colored symbols, thick and circular and symmetrical. the next time I’m there, though, I’ll take a closer look.

Your description doesn’t match anything I recall seeing in a Hindu household. The description makes it sound kind of like Chinese or Japanese Buddhist type stuff, but I really have no idea. Don’t think they’re Hindu, though.

Thick, circular, symmetrical, colored symbols could be anything. Unless you’re more specific, we have nothing to go on.
